SIS: The importance of caffeine

Caffeine is one of the most heavily researched and beneficial ergogenic aids available. The understanding of the performance effect of caffeine has increased and this has widened its use. Most people know that “caffeine may improve performance” but what does it actually do and how can we make the most of caffeine?

Caffeine acts centrally on the brain to lower the perception of effort, which is particularly noticeable in longer events. In distance events over 90 minutes or high intensity events under 90 minutes, mental tiredness as well as physical fatigue plays a large role in determining performance as the event progresses. Caffeine can help to maintain physical performance in this situation.

Designed to provide a mental and physical boost, Science in Sport (SiS) GO Caffeine Shot is a new caffeinated shot with added Vitamin B to support a reduction in tiredness and fatigue.

Developed with professional athletes and teams, SiS GO Caffeine Shot also helps to maintain focus and concentration. Ideal for use before training or ahead of short duration events, it can also be used during exercise.
